According to the IBM Spectrum Protect documentation1, the command that is used to replicate directory-container data to a target server is A. REPLICATE STGPOOL. This command replicates data from a source storage pool to a target storage pool on another server. The source storage pool can be a directory-container storage pool, which stores data in deduplicated containers.

the UPDATE NODE command allows you to update node attributes, such as node name, password, policy domain, management class, deduplication settings, replication settings, and more1

According to the web search results, the best answer is C. compare the policies on the source and target replication servers. This command is used to verify that the policies on the target replication server match those on the source replication server1.
